CAR-ROOF.

Application filed December 13, 1918.

To all whom 'it 'may concern Be it known that we, WILLIAM A. BREWER, acitizen of the United States, and a resident of the city of Pittsburgh,county of Alle gheny, and State of Pennsylvania, and En WARD F. HoPPEL,a citizen of the United States, and a resident of the city of NewKensington, county of IVestmoreland, and State of Pennsylvzuiia, haveinvented a new and useful Improvement in Car-Roofs, of which thefollowing is a specification.

This invention relates to flexible car roofs of the type shown in C. C.Murphy Patent No. 1,133,493 dated March 30, 1915 wherein the roof sheetsare pivoted near their ridge ends to the roof sheathing and areconnected along their side and ridge margins by flexible seams and itrelates particularly to the ridge construction of roofs of this type. Inroofs of said type, the running board saddles, which support the runningboards, and

.the intermediate anchor saddles, which hold the roof sheets down ontheir respective pivv ots, are 'secured to the roof su'bstructure byineens ot' bolts; and it is important that these saddlesbe kept tight atall times to secure a water tight roof. In actual practice, these woodensaddles sometimes become loose and permit leakage; and, among theconditions which contribute to this eiiect, are i the following: therottingand wearing of the saddles around the bolt holes; the shrinkingof the saddles. roof sheathing and ridge poles' and the loosening of thenuts on the saddle bolts during the service of the car. In roofs of saidtype, another practical disadvantage is that the wooden intermediateanchor saddles, which are recessed on their under sides to receive thebosses of the roof sheets, are liable to split in the region of therecesses and thereby permit the sheets to 'become disengaged from theirpivots.

The principal objects of the present invention are: to improve the ridgeconstruction of the car so as-to overcome the disadvantages hereinbeforementioned; to eliminate the' intermediateV anchor saddles and ridgecorner caps;` to improve the joints between adjacent ends of the ridgeseam covers and the running board saddles; and to keep the verselylofthe car, side by side, in two rows ridge seam covers in alinement. Theinvention consists in an anchor c lip for holding I the sheets inposition at the rid e, and in the .improved joint between the ar )acentridge Specification of Letters Patent.

Fig. 8 is a perspective view ofthe end portion of one of the ridge seamcovers;

Fig. 9 is a perspective view of the ridge end portion of a transverseseam cover;

Fig. 10 is a vertical cross-section of the eaves portion of the roof,the section being takenthrough one of the transverse seam covers on theline 10v10 in Fig. l; and

Fig. 11 is a vertical cross-section of the eaves portion of the roof,the section being taken between transverse seams on the' line 11-11 inFig. 1.

The roof illustrated in the accompanying drawings comprises roofsheathing boards 12 supported at the eaves by metal angle side plates13, and at the ridge by means of a ridge pole 14:, all of any suitableconstruc-4 tion. T ev roof sheets 15 are arranged transon opposite sidesof the ridge. The roof sheets are arranged in pairs on opposite sides ofthe ridge', the twosheets of apair' being disposed end to end intransverse alinement and spaced a art from the adj acent pairs alongtheir side margins to permit mullions 16 to be laid between them. Thesemullions are arranged in alinement cross-wise of the car, extendtransversely of the car from eaves to ridge on opposite sides of theridge, and are of less width than the space between the side margins ofthe roof sheets.

The eaves ends of the roof sheets are turned under, as at 17,parallelwith the body portion of the sheet but spaced therefrom far enough toaccommodate the rebent inner portion 18 of a continuous flashing strip19. The ashing strip 19 lies in a rabbet formed in the eaves end of theroof sheathing and is turned down over the eaves ends of the sheathingand angle side plate 13. The flashing strip 19 and the eaves ends of theroof sheathing 12 are secured to the side plate by bolts 10 (see Fig.10) or other suitable securing means, which are preferably located underthe eaves ends of the mullions 16. The side and ridge margins of theroof sheets are provided with inwardly hooked upstanding flanges 20 and21. The side margins of adjacent roof sheets are covered by transverseseam covers 22 which are supported on the mullions 16 arranged betweenthe spaced side margins of the roof sheets. These transverse seam coversare of inverted channel shape in cross-section and their side walls haveinturned flanges 23 at the bottom which incline upwardly and interlockwith the inwardly hooked upstanding side flanges 2O of adjacent roofsheets. The transverse seam covers extend from ridge to eaves and areheld down at the eaves ends by bending the eaves ends 24 of their topportions down over the ends of the mullions and then turning saidportions under the rebent inner portion 18 of the flashing strip 19. Thetop portions of the ridge ends of the transverse seam covers have flatextensions 25 which lap at the ridge and are perforated to receive thesaddle bolts 26 of the running board saddles 27. Running boards 27al aresecured to the running board saddles 27, which rest on the transverseseam covers 22 and are supported by the mullions 16, thus leaving thesheets free to move under the transverse seam covers.

Each pair of oppositely disposed roof sheets 1s pivoted to the roofsubstructure at the middle portion near its ridge end by means of asheet metal pivot saddle 28. The pivot saddles straddle the ridgeportion of the car and are provided near their ends with inverted cupshaped pivot bosses 29 which lit into :counterpart upstanding bosses 30formed in the middle portion of the sheets near their ridge ends. Thebosses 30 of each pair of oppositely disposed roof sheets are held in'engagement with the pivot bosses 29 of the pivot saddle 28 by means of achannel shaped anchor clip 31 which has the upper portions of its sideflanges bent outwardly and downwardly over the adjacent ridge flanges 21of the oppositely disposed roof sheets. These anchor clips are locatedon top of the pivot plate 28, and both of these members arc secured inplace by means of a bolt which extends down through the rootI sheathingand ridge pole.

A ridge cover 83 similar in cross-section to the transverse seam covers22, but of greater width, straddles the spaced ridge margins of eachpair of roof sheets, and the lower edges of its side walls rest on theroof sheet and are rebent inwardly, terminating in upwardly inclinedflanges 34. The side walls of the ridge seam covers extend fromtransverse seam cover to transverse seam cover and at each end their topportions have extensions 35 which project over the lapped extension 25of the transverse seam cover to within a short distance on each side ofthe saddle securingbolt 26. The extensions 35 at each end of the ridgeseam covers have npstanding flanges 36 at their ends which project intovertical saw cuts or grooves 37 cut in the under side of the runningboard saddles 27. y

The adjacent ends of the ridge caps are held in alinement by means ofridge cover connector plates 38 which rest on the lapped extensions 25of the transverse seam covers and project a short distance into theadjacent ends of the transverse seam cover be-y neath the top portionsofthe same. The margin of the portions of the connectoiil plates whichproject beneath the adjacent end of the ridge seam covers are rebeiit toform stiffening flanges 39. The connector plates are held in position bymeans of the saddle bolts 26 which pass through holes surrounded byupstanding bosses 40 located in the center of the connector plates. Thebosses 40 of the connector plates are drawn into the under side of therunning board saddle when the nut on the lower end of the saddle bolt isdrawn up tight. The connector plates2 which serve to keep the ridge capsin alinement, will also carry off water that may be blown in under therunning hoard saddles and over the upstanding flanges at the ends of theridge seam covers, while the upstanding boss 40, which projects into theunder side of the running board saddles, prevents this water from'following the bolt and reaching the interior of the car. The sheets areheld in position on their pivots at the ridge by the anchor clips 3l,thereby eliminating the intermediate running board saddles heretoforeused for this purpose. The sheets are further held down along the ridgeby the wide ridge seam covers, which bear on the roof sheets close tothe bosses. The transverse seamcovers ridge seam covers 33 are heldagainst move- `ment: lengthwise of the car by the upstamling llanges 36at their ends which fit into the grooves or saw cuts 37 in the underside of the running board saddles 27. By the arrangement described, eventhough the ruiming board saddles become loose, the water proofingqualities of the joints along the ridge will not be impaired.

The invention is not restricted to the particular shapes andarrangements of parts shown in the drawings.
